Mobile adhoc networks are dynamic in nature in such a way that the nodes which are wirelessly connected for communicating with each other are uncertain with its mobility. They have limitations with respect to processing capability, power and so on. These limitations hinder the efficient usage of these nodes in power intensive applications. In this scenario, the necessity to improve the quality of service of the accumulated mobile nodes emerges. Clustering is a process which is used to group a number of mobile nodes and make them manageable under a single node which is termed to be as cluster head (CH). Clustering improves the network scalability, as a result, improves the throughput, packet delivery ratio and so on. The process of clustering and cluster head election differs, based on the parameters considered. The advantage of improving the network efficiency through clustering entirely depends upon the process of clustering and electing heads for those clusters. In this paper we focus on electing efficient cluster heads for cluster of nodes by Dynamic clustering process (DCP). We use a Dynamic range clustering which clusters the network and uses a variable weight function for the purpose of selecting head node for the cluster. This is based on the node density and bandwidth utilization. In addition to that a ‘Hello’ message is transmitted by each mobile nodes and we define a term Cluster head Prowess (CHP) which represents the dexterity of a mobile node to take the role of a head in its cluster. The performance of the proposed methodology shows promising results in reducing the delay, packet loss probability and re-clustering instances.
